Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 32 points:

(1,2,6,10)(3,11,14,15)(4,9,5,8)(7,12,16,13)(17,18,21,23)(19,25,26,32)(20,28,30,24)(22,29,31,27);(1,3,6,14)(2,7,10,16)(4,13,5,12)(8,11,9,15)(17,19,21,26)(18,22,23,31)(20,29,30,27)(24,32,28,25);(20,30)(27,29);(1,4,6,5)(2,8,10,9)(3,12,14,13)(7,15,16,11)(18,23)(19,26)(24,28)(27,29)
